Probe the safety status of your electric circuit with this multifunction tester accessory from Megger. It's a test lead set with three interchangeable tips – standard shrouded, removable shrouded and extended probe tip – so it's a versatile choice. Connect the leads to a Megger MFT1552 series electrical tester (611-5704) to safely carry out loop, RCD and insulation tests.

• Shrouded probe tips offer user protection against electrical hazards
• Extended probe tip makes it easier to access cables in awkward places

• Laboratories
• Automotive engineering
• Power supply units
• Electronics testing
• Repair workshops

A loop and RCD tester combines the function of two meters into one handy unit. The loop testing measures how resistant the earth conductor is to overcurrents and short-circuits, while the RCD testing ensures that the power supply's cut off when it senses earth leakage. Testing for these parameters improves electrical and fire safety.

The leads are maintenance-free, but it's recommended you store them along with the tips inside your tool bag or the tester's carry case to prevent damage.
